I've added ScaleImageLabel to swipe Tabs. I want to calculate amount of time each tab remains in focus. I added focus listener to Tabs/ScaleImageLabel but it's not getting fired. It's working when added to the form. Any suggestions on how to achieve it?
If I understand correctly what you need is a tab selection listener. Focus listener will only work for focusable components and labels are by default non-focusable. I would recommend avoiding it since focus is used for key based navigation. It might produce different results than you would expect.
I am trying to place a paper-dropdown inside a collapsable iron-list (similar to the demo here). But when I click on the dropdown menu, the menu items are displayed at a completely incorrect location. Below is a JSBin example of what I am seeing. If I place the same dropdown outside of the iron-list or even in paper-dialogs, they are working fine.
Can someone tell me whats going wrong or if there is any workaround.

I am unable to fire OnItemClicklistner method on clicking on Checkbox (in my List-view), i have tried following way...
i have set the focusability and clickability to false as follows.
android:focusable="false"
android:clickable="false"
android:focusableInTouchMode="false"
It fires the OnItemClicklistner but doesn't send reference of Checkbox in view parameter. Please help on this.
Please look at Google documentation at CheckBox class.
Checkbox does not have OnItemClicklistener. You may be getting events from a different UI element, hence confusing you. Checkbox has setOnClickListener method for you to use. Remember documentation is there to help you.
Right now I have change listener but it requires the checkbox to lose focus to register. I looked around online and was unable to find out if such listener (or better substitute) exists.
Is there anyway at all to create a click listener?
Have you tried check?

I've created a Google like SearchBox control in Silverlight. That means, as I type in the box, a DropDownListBox appears just below the SearchBox, showing all the items that match with the text I've typed in searchbox so far (i.e AutoComplete feature), exactly like this:
Now, I want to add a functionality to it : I want to make the DropDownListBox to disappear, as soon as user clicks outside it, or anywhere on the screen. I cannot handle MouseLeftButtonDown (or any such event) in other controls, to accomplish this, because users can click anywhere, including non-silverlight region. Can anybody suggest me what should I do to achieve this?
So my question basically is:
How to know if user has just clicked and the click event occurred outside a particular control?
Please note that AutoCompleteBox doesn't serve my purpose. So I cannot use it.
I have a feeling that working with LostFocus event can solve your problem.
I guess this question is a bit old, but i just stumble upon trying to do the same and finding a solution. This is what i did
Created a Border with All Margins -500, this will cover the full screen essentially.
On Click Behaviour of this Border, the dropdown section of SearchBox
is collapsed.
Adjust z-Index of Border just below the SearchBox and DropDown
section, so clicking on SearchBox or DropDown wouldn't close it.
Set Border Visibility Collapsed, and make it visible when DropDown is Visible.
I hope it helps someone who is looking for the similar problem.
